Other Interfaces Enter specific settings and addresses to identify devices in the other tabs, if neces-
sary, or check the preset values.
Device addresses are used by the system to identify each device and must be unique
throughout the substation. Detailed instructions for setting the interfaces are available
in the “DIGSI
®
4 Communications” manual.
If you desire to expand or modify interfaces later, refer to the modification instructions
for the interfaces, and if necessary for the hardware, see also instructions in Sub-sec-
tion 8.1.3 of this manual.
